A 1TB M.2 2280 SATA SSD with 3D NAND delivering up to 560 MB/s reads and 530 MB/s writes for consumer desktops and laptops
The WD Blue WDS100T2B0B is a 1TB internal solid-state drive built for everyday computing. Its M.2 2280 form factor fits modern laptops and desktops that need a compact storage upgrade. 3D NAND technology delivers reliable capacity for operating systems, applications and personal files.
This drive connects through the SATA III 6Gb/s interface, capping sequential reads at 560 MBps and writes at 530 MBps. Random performance reaches 95,000 IOPS read and 84,000 IOPS write for responsive multitasking. The SATA link is the single specification that determines whether the drive matches your system.
Average active power sits at 60 mW with idle consumption as low as 12 mW in DEVSLP, leaving more battery capacity for other components. The drive operates from 0 to 70 °C and requires no extra cooling or mounting hardware beyond a standard M.2 slot. Free Western Digital software adds drive monitoring and cloning tools.

The 560 MB/s read ceiling is the SATA III interface limit; real-world loads such as game level loads or large file copies will typically sit a little below that figure.
SATA III tops out at 6 Gb/s, so even though the drive uses the M.2 2280 form factor it cannot exceed roughly 560 MB/s read and 530 MB/s write.
It needs an M.2 key-M or key-B slot that accepts 2280-length modules and a single screw to secure the drive at the far end.
